Katherine Jackson’s attorney, L. Londell McMillan, says the Jackson family and its matriarch have decided to bring in a new set of attorneys to handle the case.

McMillan, who is Katherine Jackson’s personal attorney, declined to say who would take over the case. The change will be discussed at a court hearing Thursday afternoon in Los Angeles.

Katherine Jackson is one of the primary beneficiaries of her son’s estate and the legal guardian of his children. Her former attorneys had been considering mounting a challenge to the authority of the men administering the estate.
